The present invention relates to polyimide powder and a manufacturing method therefor. Being polymerized from diamine monomers and dianhydride monomers using graphene, the polyimide powder according to the present invention exhibits electroconductivity whilst having minimal reduction in tensile strength and elongation, and thus can be provided as a polyimide powder capable of preventing static electricity.
